First let us recall some more historic highlights about the origin and current charactarizations of the pseudo-arc. Answering a question of Mazurkiewicz [1]} in the negative, whether the arc is the only continuum homeomorphic to all of its non-degenerate subcontinua, in 1948 Moise [2]} constructed a “new” example of a space with the same self-similarity property, which he named a pseudo-arc. The same year Bing [3]} constructed a “new” example of a homogenous indecomposable continuum. Ten years later Bing [4]} published a paper where he proved that all three spaces constructed independently by Knaster, Moise and himself are homeomorphic. Bing [5]} showed that in the Baire category sense the pseudo-arc is a generic continuum. Namely, he showed that for any manifold \(M\)  of dimension at least 2, the set of subcontinua homeomorphic to the pseudo-arc is a dense \(G_{\delta }\)  subset of the hyperspace of all subcontinua of \(M\) . This phenomenon resembles the one of irrational numbers in \(\mathbb {R}\) : seemingly atypical objects in the space are in fact generic.
